Henry V - Rex of Anglie from 1 September 1422 to 4 March 1461
Henry V was King of England from 1413 until his early death in 1422. He was the second English monarch of the House of Lancaster. Despite his relatively short reign, Henry's outstanding military successes in the Hundred Years' War against France made England one of the strongest military powers in Europe.

In 1415, Henry embarked on war with France in the ongoing Hundred Years' War (1337–1453) between the two nations. His military successes culminated in his famous victory at the Battle of Agincourt (1415) and saw him come close to conquering France. Taking advantage of political divisions within France, he conquered large portions of the kingdom and Normandy became English for the first time in 200 years. After months of negotiation with Charles VI of France, the Treaty of Troyes recognised Henry V as regent and heir apparent to the French throne and he was subsequently married to Charles's daughter, Catherine of Valois.

Following this arrangement, everything seemed to point to the formation of a union between the kingdoms of France and England, in the person of King Henry. His sudden and unexpected death in France two years later condemned England to the long and difficult minority of his infant son and successor, who reigned as Henry VI in England and Henry II in France.
